Detailed Description

Macro Definition Documentation

◆ SIP_SUBSCRIPTION_STATE_INIT

#define SIP_SUBSCRIPTION_STATE_INIT ( )

Initializer for structure sip_subscription_state_t.

A static sip_subscription_state_t structure for Subscription-State header must be initialized with the SIP_SUBSCRIPTION_STATE_INIT() macro. For instance,

#define sip_subscription_state(sip)
Access a SIP Subscription-State header structure sip_subscription_state_t from sip_t.
Definition sip_protos.h:9175
#define SIP_SUBSCRIPTION_STATE_INIT()
Initializer for structure sip_subscription_state_t.
Definition sip_protos.h:9192
Structure for Subscription-State header.
Definition sip.h:727

◆ SIPTAG_SUBSCRIPTION_STATE

#define SIPTAG_SUBSCRIPTION_STATE (   x)

Tag list item for pointer to a Subscription-State header structure sip_subscription_state_t.

The SIPTAG_SUBSCRIPTION_STATE() macro is used to include a tag item with a pointer to a sip_subscription_state_t structure in a tag list.

Parameters
xpointer to a sip_subscription_state_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_SUBSCRIPTION_STATE_REF().

◆ SIPTAG_SUBSCRIPTION_STATE_STR

#define SIPTAG_SUBSCRIPTION_STATE_STR (   s)

Tag list item for string with Subscription-State header value.

The SIPTAG_SUBSCRIPTION_STATE_STR() macro is used to include a tag item with a string containing value of a sip_subscription_state_t header in a tag list.

Parameters
spointer to a string containing Subscription-State header value, or NULL.

The string in SIPTAG_SUBSCRIPTION_STATE_STR() can be converted to a sip_subscription_state_t header structure by giving the string s has second argument to function sip_subscription_state_make().

The corresponding tag taking reference parameter is SIPTAG_SUBSCRIPTION_STATE_STR_REF().

Function Documentation

◆ sip_is_subscription_state()

int sip_is_subscription_state ( sip_header_t const *  header)
inline

Test if header object is instance of sip_subscription_state_t.

Check if the header class is an instance of Subscription-State header object and return true (nonzero), otherwise return false (zero).

Parameters
headerpointer to the header structure to be tested
Return values
1(true) if the header is an instance of header subscription_state
0(false) otherwise

◆ sip_subscription_state_copy()

sip_subscription_state_t * sip_subscription_state_copy ( su_home_t home,
sip_subscription_state_t const *  hdr 
)
inline

Copy a list of Subscription-State header header structures sip_subscription_state_t.

The function sip_subscription_state_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be copied

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

Example
subscription_state = sip_subscription_state_copy(home, sip->sip_subscription_state);
sip_subscription_state_t * sip_subscription_state_copy(su_home_t *home, sip_subscription_state_t const *hdr))
Copy a list of Subscription-State header header structures sip_subscription_state_t.
Definition sip_protos.h:9322
Returns
A pointer to newly copied header structure, or NULL upon an error.

◆ sip_subscription_state_dup()

sip_subscription_state_t * sip_subscription_state_dup ( su_home_t home,
sip_subscription_state_t const *  hdr 
)
inline

Duplicate a list of Subscription-State header header structures sip_subscription_state_t.

Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
subscription_state = sip_subscription_state_dup(home, sip->sip_subscription_state);
sip_subscription_state_t * sip_subscription_state_dup(su_home_t *home, sip_subscription_state_t const *hdr))
Duplicate a list of Subscription-State header header structures sip_subscription_state_t.
Definition sip_protos.h:9279
Returns
A pointer to the newly duplicated sip_subscription_state_t header structure, or NULL upon an error.

◆ sip_subscription_state_format()

sip_subscription_state_t * sip_subscription_state_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a Subscription-State header from formatting result.

Make a new sip_subscription_state_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_subscription_state_t.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Returns
A pointer to newly makes header structure, or NULL upon an error.

◆ sip_subscription_state_init()

sip_subscription_state_t * sip_subscription_state_init ( sip_subscription_state_t  x[1])
inline

Initialize a structure sip_subscription_state_t.

An sip_subscription_state_t structure for Subscription-State header can be initialized with the sip_subscription_state_init() function/macro. For instance,

sip_subscription_state_t * sip_subscription_state_init(sip_subscription_state_t x[1])
Initialize a structure sip_subscription_state_t.
Definition sip_protos.h:9210

◆ sip_subscription_state_make()

sip_subscription_state_t * sip_subscription_state_make ( su_home_t home,
char const *  s 
)
inline

Make a Subscription-State header structure sip_subscription_state_t.

The function sip_subscription_state_make() makes a new sip_subscription_state_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Returns
A pointer to newly maked sip_subscription_state_t header structure, or NULL upon an error.

Variable Documentation

◆ sip_subscription_state_class

msg_hclass_t sip_subscription_state_class[]
extern

Header class for Subscription-State header.

The header class sip_subscription_state_class defines how a SIP Subscription-State header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_subscription_state_t header structure.
